A beam of electrons traveling with a speed of 3.00 x 107 m/s enters a uniform, downward electric field of magnitude 1.17 x 104 N/C between the deflection plates of an oscilloscope (the figure below ). The initial velocity of the electrons is perpendicular to the field. The plates are L = 6.50 cm long. What is the magnitude of the change in velocity of the electrons while they are between the plates?
How far are the electrons deflected in the �y-direction while between the plates?
